It is evident thattliere may. be any number of spacingl Ymenniei's desired and said members may be of varying lengths according to the nature of the work which the cylinder gauge is `to be used.

The general operation of the device hereinbeforedescribed is as follows z-Assuming that the cylinder gauge and handlel, which latter embodies therein the set-ting tool, are all assembled as illustratedin Fig. 1, and it is desired to measure the diameter of the .bore ofa cylinder, the firstfstep is to remove the portion of the device which constitutefsthe lsetting tool by disconnecting the latter from the-rod 18 at 23.V

The nut is then removed from the reduced portion-27 ofthe member 25 and the spacing members 29,` 30, 31 and 32 and setting finger 28 yare rearranged as required to make the distance between the faces a and Z) of the-setting iinp gers 21 and 28 respectively equal to the exact Yeo diameter of the bore to be measured. A contact point 12 is lthen* att-ached to the yielding'contact `member 11 which will malte the distance between the extremities of the con- 'tact'points 10 and 12 'equal the distance between the surfaces V0L 'and of the setting l' fingers 21 and 28. The cylinder gauge is now jpositionedbetween the fingers 21*V and 28 of the setting tool, asillustrated in Figs.

2 and 3 and the `dial 7 adjusted ink a well known manner, so that the indicating hand 9Vwill register Zero, as illustrated in Fig. Vv3.

The settingV ytool is then again. attached to the` rod 18 and utilized as a handle for the cylinder gauge and when said cylinder gauge is inserted in the bore of the cylinder, the dial 7 will show the amountJ of over or under sizes in said cylinder kas compared to the distance `between the surfaces a and b of the settin tool.

I cv aim 1. A setting tool for gauges comprising in combination, a beam having` a reduced por-l tionv vforming a shoulder intermediate the length of the beam, a fixed setting finger carried by said beam at one end thereof, a movping member and projecting laterally therefrom at' one end thereof, a memberfdetachthe other end thereon-a second setting finger mounted upon said detachably mounted ably mounted'upon Vsaid gripping member atl tends, said opening member and projectingflaterally therefroml and a plurality of Ispacing members also mounted upon said detachably mounted (iti member and adapted to varythe .distance between said .spacing fingers. n

8. A setting tool for gauges comprising,

in combination, a gripping member, a setting finger rigidly mounted upon said gripping memberV and projecting laterally therefrom atoneend thereof, a member detachably mounted upon said gripping member at the other en olthereof, a second `set-ting nger mounted upon said detachably mount- .f
